XSetCloseDownMode(3) XLIB FUNCTIONS XSetCloseDownMode(3)
NAME
XSetCloseDownMode, XKillClient - control clients
SYNTAX
int XSetCloseDownMode(Display *display, int close_mode);
int XKillClient(Display *display, XID resource);
ARGUMENTS
close_mode
Specifies the client close-down mode. You can pass Destroy-
All, RetainPermanent, or RetainTemporary.
display Specifies the connection to the X server.
resource Specifies any resource associated with the client that you
want to destroy or AllTemporary.
DESCRIPTION
The XSetCloseDownMode defines what will happen to the client's
resources at connection close. A connection starts in DestroyAll mode.
For information on what happens to the client's resources when the
close_mode argument is RetainPermanent or RetainTemporary, see section
2.6.
XSetCloseDownMode can generate a BadValue error.
The XKillClient function forces a close down of the client that created
the resource if a valid resource is specified. If the client has
already terminated in either RetainPermanent or RetainTemporary mode,
all of the client's resources are destroyed. If AllTemporary is speci-
fied, the resources of all clients that have terminated in RetainTempo-
rary are destroyed (see section 2.5). This permits implementation of
window manager facilities that aid debugging. A client can set its
close-down mode to RetainTemporary. If the client then crashes, its
windows would not be destroyed. The programmer can then inspect the
application's window tree and use the window manager to destroy the
zombie windows.
XKillClient can generate a BadValue error.
DIAGNOSTICS
BadValue Some numeric value falls outside the range of values accepted
by the request. Unless a specific range is specified for an
argument, the full range defined by the argument's type is
accepted. Any argument defined as a set of alternatives can
generate this error.
